Replacing Your AC? Consider a Heat Pump.

A heat pump cools exactly like an air conditioner and heats your home too. With a ComEd instant discount of up to $2,000 on a qualifying ducted system, the difference in price is often smaller than you’d expect. See heat pumps or ComEd instant discounts.

St. Charles, Geneva and Batavia run their own electric utilities, so ComEd’s heat pump discounts aren’t available there.

Air Conditioning Repair & Installation FAQs

How long does a central air conditioner last?

A central air conditioner typically lasts 12 to 17 years, depending on how well it’s maintained and how hard it works.

Why is my AC freezing up?

Ice usually points to restricted airflow, like a clogged filter or dirty coil, or to a refrigerant problem. Turn the system off to let it thaw and call us so we can find the cause.

What is R-32 refrigerant?

Newer Amana and Daikin systems use R-32, a lower global warming potential refrigerant than the R-410A in most systems installed before 2025.

How long does an AC replacement take?

Most residential air conditioner changeouts are done in a single day.

Do you repair air conditioners you didn’t install?

Yes. We repair and maintain all major brands of central air conditioners, no matter who installed them.

Can I finance a new air conditioner?

Yes. You can prequalify in about 2 minutes with no impact to your credit score.
